WIRE-PAINTING nnusm Specification of Letters latent.

Application filed pm 11, 912; Serial No. ceases To all tbhom may concern k J. CQCHRAN, acitizen of the United States, residin at Monessen, in the countyof Westmore and and State of Pennsylvania, have invented certain new and useful Improvements in Wire-Painting Brushes;. and I do declare the following to be a'full; clear, and exact description of the invention, such as will hill enable others skilled theart to'which it appertams to "make and use the same,

I Thisinvention relates-to' fountain brushes,

and'fmore es ciallylto-those intended'fo'r the use of pa nt; and the object ofthe' same is to' produce a brush of this. character by vDrieans Qf which one may: :pai'nt' smooth, barbed, or twisted fence wire or metallic fence ribbon. This 'objectiis" accomplished by' constructing the brush'as" hereinafter more fully described'and claimed, and as shown thei drawings wherein- Figure 1 is' aside elevation of this'device complete, showing the brush itself in the position it occupies, when paint is to be applied to a fence wire. FIg;-2"'isabottom plan view of the brush. Fig. 3 is acentral longitudinal sectional view through the handle andgthe partsat both ends thereof. Fig. tis an enlarged'verticahsectional view through thehuhs of the -two rotar ".brushes andjthrough the-guide plates whic connect the extremities of the forkKar-m on which saidhubs are mounted. g g

In the' drawings the-numeral 1 designates 'a reservoir or tank having loops 2 to which is connected a strapinte'nded to pass over the shoulders otthe use and theupper end of this'tank is losedlby a screw cap 3 havin a nipple 4; to which is attached an ai'r'pum "fitso'that pressure may be 'put on the paint contained within, the tank in order to cause it to flow reliably 'to the brush. The outlet 6 from the tank is controlled by a valve "2',v and to the latter is attached 'a hose .8 which leads toa coupling '9' adapted to ,be connected with the "handle of the brush proper.

The handle comprises a tubular hand hold 10 from whose frontor outer end probeing controlled by a spring-actuated thumb s 16 on the lever. l pivoted at 15 between lu handle and having a forked en 17 loosely embracing the upper end of the valve plug.

at 18, and its extremity is turned downward as at 19 soas to deliver on the uppermost brush. The head of this improved brush comprises two rotary brush-heads 20 and 21, the former dis osed immediately above' the other, and eac having a hub 22 journaled on the outturned extremity of one of the fork arms and held there by means of a cot: ter' pin 23 or other detachable *fastening de Vice. .The size of these brushes is such that normally their bristles contact, so that rotation of one imparts rotation to the other. Between the outturned extremities of the fork arms is disposed an extensible guard consisting of two plates 24 and 25 overlapping each other, one provided with slots 26 while the other has screws 27 en aging said slots so that the plates may be a justed over each other to take up for wear in the bristles of the two brushes; and both plates are flanged and bent inward at their ed es as" at 28.

same. Ordinarily considerable aint will 1 accumulate within a hand held w ichis of proper size, and the same acts as a supple mental reservoir to contain the paint forced down the flexible tube by the air pressure in the main tank,-andj as a result it may occur.

that particles of paint or sediment accumulate in the handle so that this plug is providedfor'permitting access thereto and allowing the interior thereof to be cleaned from-time to time. V

I In use, th tank is, filled almost full of paint of the proper'color and consistency, air pressure-applied, andv if the pump be removable itis'detached and the nipple closed.

' The valve in thefout-let is then opened and paint flowsdown the flexible-tube, through the "coupling, and into the hand hold 10, out of which it cannot pass through the ductile tube because of the spring closed valve 13,

With the tank su ported upon his shoulder the and hold in one hand, the

-'and graspin g holds the uppermost brush 20 operator now vertically disposed above the lowermost "brush21, and pushes the two brushes toward the fence wire so that the latter passes between them and strikes the, ard. t Then drawing the brush as a who e along the fence, the passage of the wire betweenits two brushes causes them to rotate around. their axes. Meanwhile with his thumb upon the .thumb piece of the controlling valve, he opens the latter to a' sufiicient extent to allow some paintto flowout' the duotile tube and upward out hisnozzle onto the top of the upperbrush, and the rotation of the latter carries the paint around onto the fence wire and onto the upper side ofthe lower brush which in turn carries the paint around its periphery "and onto the. lower side of the wire. This action is repeated for each strand of the wire in the fence, and when a post is encountered the brushes can I be drawn off the wire and -the surface of the post painted bypassing up and down it what might be called the outer edges of the two rotary brushes which are now of, course well covered with paint. In' a short time the operator will learn to regulate the flow of 1paint by pressure on the thumb piece and wi 1 feed to the brushes just suflicient'paint .to cover the surface being treated, without between them. Moreover, when the bristles of the two-brushes become worn, the twomembers of the guard may be adjusted to draw the extremities of the fork arms nearer together, as it is intended that the bristles of the two brushes shall just about touch each other and shall certainly overlap the fence wire being treated to a sufficient extent to provide for painting the side edges of each strand of wire. a

\ I do not limit myself to the materials or nected therewith,.a fork whose arms stand one above the other and have their extremities outturned' in parallelism, a tube leading from the handle along the uppermost arm and bent thence upward and downward, and a controlling valve in said tube; of a .pair of rotary'brushes each having a hub mounted on one of said outturned extremities, and a'guide connecting the latter ,and consisting of two plates whose outer ends engage said extremities and whose bodies are overlapped, one of them being provided with slots, screws in the other plate adjustably mounted in said slots, and flanges along both edges of both plates deflected away from said brushes.

2. In a machine of the class described, the combination with a tubular handle, afork whose arm stand one above the other, a tube leading from the front end of the handle to a pointabove the uppermost forkarm, and means for supplying paint to the other end of the handle; of a pair of rotary .brushes each having a hub mounted on one of the fork arms, and a guide connecting the latter and consisting of two plates whose outer ends engage sald arms and whose bodies are overlapped, means for adjusting them where they overlap, and flanges along both edges of both plates deflected away from said brushes:

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
